Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2015-10-13 to 2016-02-10
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: IEC 60079-20-1, Section 7
- Deviations:
- yes
- Remarks:
- With 5°C inrements rather than the specified 2°C increments
- GLP compliance:
- yes
- Key result
- Auto-ignition temperature:
- 405 °C
- Atm. press.:
- >= 747 - <= 756 mm Hg
- Conclusions:
- The Auto-Ignition Temperature (AIT) of the test substance = 405 ± 20°C.
- Executive summary:
Room temperature: 21 - 22°C Atmospheric pressure: 747 - 756 mmHg Sample preparation: tested as received
The results, giving the lowest ignition temperature and corresponding no-ignition temperatures obtained from five test series.
Sample quantities from 25, 50, 70, 100 and 150µL were tested at 400°C with an ignition delay > 300 s. There was no ignition observed.
Only when a 50µL sample was tested at 405°C an ignition occured with an ignition delay of 10 s.

- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 405 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
